ABSTRACT
The temperature dependent dielectric response of <001>-oriented 91% Pb(Znâ…“Nbâ…”)O3-9% PbTiO3 single crystal has been studied at various frequencies. A dielectric relaxation process with a broad distribution of time constant has been observed below 180 K. The peak temperature of the dielectric loss can be fitted well with Volger-Fulcher relation. We assume this relaxation process can be attributed to the freezing of ferroelectric macrodomain walls induced by the pinning of point defects.
